       x: An Splus object 

gridlist: A list with as many components as variables describing the
          surface. All components should have a single value except the
          two that give the grid points for evaluation. If the matrix
          or data frame has column names,  these must appear in the
          grid list. 

  extrap: Extraplolation beyond the range of the data. 

     ...: Method for specific class of data  may have additional
          arguments.
